ios::right only works once C++ -

i have no idea why ios::right works once. totally nothing

same problem ios::hex, ios::decimal , few others unless insane codes , them magically work again

#include <iostream> #include <iomanip>  using std::cout; using std::ios;  int main() {     int len;     std::cin >> len;     // w = len + 1;     cout.width(len);     cout.setf(ios::right);     (int s = 0; s < len; s++) {         (int c = 0; c <= s; c++) {             cout << '#';         }         cout << '\n';     }        std::cin.get();     std::cin.get(); } 

expected output:

     #     ##    ###   ####  ##### ###### 

what get:

     # ## ### #### ##### ###### 

tried this:

cout << ios::right << '#'; 

didn't work.

you need write cout.width(len-s);cout.setf(ios::right); inside first loop because ios::right works 1 time. should

#include <iostream> #include <iomanip>  using std::cout; using std::ios; int main()  {   int len;   cin >> len;   (int s = 0; s < len; s++)   {      cout.width(len);      cout.setf(ios::right);      (int c = 0; c <= s; c++)      {        cout<<"#";      }      cout<<"\n";   }   std::cin.get();   std::cin.get(); } 

but code not correct per required output , correct code :

#include <iostream> #include <iomanip>  using std::cout; using std::ios; int main()  {   int len;   cin >> len;   (int s = 0; s < len; s++)   {      cout.width(len-s);  // align      cout.setf(ios::right);      (int c = 0; c <= s; c++)      {        cout<<"#";      }      cout<<"\n";   }   std::cin.get();   std::cin.get(); }
